Problems solved by technology

[0005] However, this reflective field emission backlight structure will cause the generated light to scatter after reflection, making the halo in the area too large to be concentrated, so that the effect of lighting up a specific area must be achieved during display control. not easy
Therefore, it is impossible to achieve high contrast characteristics of liquid crystal display, which reduces the advantages of field emission backlight

Embodiment Construction

[0034] In the present invention, the reflective layer is structured as a bowl-shaped structure with a light-gathering effect, so as to improve the lighting effect of its area and make the field emission reflective backlight module more competitive.

[0035] First, please refer to Figure 1A , which is a structural schematic diagram of the field emission backlight module of the present invention. The field emission backlight module includes several main parts: a first substrate 110 , a bowl-shaped reflective structure composed of a plurality of bowl-shaped reflective structures 120 and a fluorescent layer 140 . Wherein, a plurality of field emission light sources 112 are disposed on the first substrate 110 , which can emit the first light 200 . The bowl-shaped reflective structure 120 is disposed on the second substrate 130 and faces the field emission light source 120 . The fluorescent layer 140 is disposed on the bowl-shaped reflective structure 120 . The fluorescent layer 140...

Abstract

The invention discloses a method for making a field emission backlight module, a display unit, and a bowl-shaped reflecting structure. The field emission backlight module comprises a substrate and the bowl-shaped reflecting structure, wherein the substrate is provided with a plurality of field emission light sources; the bowl-shaped reflecting structure is composed of multiple bowl-shaped reflecting structures and a fluorescent layer configured thereon; the bowl-shaped reflecting structure faces the field emission light source; and the fluorescent layer is arranged upon the bowl-shaped reflecting structure and located between the bowl-shaped reflecting structure and the field emission light source.

Description

technical field [0001] The invention relates to a backlight source, in particular to a field emission backlight module, a display device and a manufacturing method of a bowl-shaped reflective structure. Background technique [0002] The field emission display (FED) made by using the characteristics of field emission electrons can be applied to the thin planar structure of liquid crystal display (LCD). Both are superior to the cold cathode line light source (CCFL) lamps of traditional liquid crystal displays. Therefore, a field emission backlight (Field Emission Backlight, FEB) is quite suitable as a backlight module of a liquid crystal display. [0003] The reflective backlight is to deposit the phosphor layer on the reflective layer (which can be aluminum or silver, etc.), and after being excited by the electron beam from the cathode field emission source, the phosphor layer will emit light, and the reflective layer can reflect the backlight to the cathode surface , so th...
